Said former NFL quarterback Jake Delhomme when I spoke to him Tuesday night: “Mike truly believes in that. Under him, you won’t just play for the Chargers, you’re family. You’re proud of that.”

Wow.

In a two-week span, this franchise’s top two football positions have undergone a face-lift simply by virtue of getting almost a half-century younger and a lot more charismatic.

Personality won’t make up for left tackle Jared Gaither’s lack of a spine. A commanding presence won’t sign right guard Louis Vasquez on its own. Friendliness won’t make wide receiver Robert Meachem a better fit for the offense.

McCoy and Telesco are signed to four-year contracts. They may or may not survive, may or may not thrive.

Turner’s .578 winning percentage as Chargers head coach is second-best among the 14 coaches in franchise history. The team averaged more than 9½ victories in 10 years under Smith’s direction.

Change is no guarantee of success. But the Chargers were just 24-24 over the previous three seasons, and change was necessary. This is certainly change.
